Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed August 12, 1919. Serial No. 316,955.

To all ill/tom it may concern:

lie it known that l, Florin l sno, citizen if of the United States,residing at Flint,

county of Genesce, State of Michigan, have invented a certain new anduseful Improvement in Motor-Sleighs, and declare the following to be afull, clear, and exact descrip tion of the same, such as will enableothers skilled in the art to which it pertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to motor sleighs shown in the accompanying drawingsand more particularly described in the following specification andclai1nz- The object of this invention is to provide a motor drivensleigh, simple in its construction and operation, and which is adaptedto operate in a heavy or relatively light fall of snow ;means beingprovided where by the screw propeller shafts, which act upon the snow,may be raised or lowered to adapt them to the depth of the snow overwhich the sleigh is to travel.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes may be made inthe precise embodiment of the invention herein disclosed, withoutdeparting from the spirit of the same.

in the accompanying drawings forming part of this specification Figure 1is a side elevation of the motor sleigh.

Fig. 2 is a plan view of the same.

Fig. 3 is a longitudinal vertical sectional view of the rear part of thesleigh. on line 33 of Fig. 2.

Fig. 4 is an enlarged detail sectional view on line l of Fig. 2, showinga part of the means employed for raising and lowering the screwpropeller shafts.

F ig. 5 is a detail view of the n'lanually operated shaft controllingthe means for raising and lowering the propeller shafts, shown in thepreceding figurethe view also showing the steerin wheel for controllingthe direction taken the sleigh.

7-7 of Fig.

Fig. 6 is a detail cross sectional view on line 6-6 of Fig. 2, showingmeans for revolving the screw propellers.

Fig/Z is a cross-sectional view on line 2, of a detail of the steeringmechanism.

Fig. 8 is a detail sectional view on line 88 of Fig. 2, showing themanner of curing the rear sled or runners to the chassis of the vehicle.

Fig. 9 is a perspective view of a detail showing the arc-shaped rack baremployed in raising and lowering the propellers.

Fig. 10 is a modification showing a driving shaft in lieu of the chainfor raising and lowering the propellers.

Referring now to the letters of reference placed upon the drawings A,denotes a vehicle chassis and B, a suitable body mounted thereon. C,indicates a forward steering sled pivotally connected by means of afifth wheel D, to the chassis frame. E, is a rearsled having brackets F,overlapping the chassis frame to which they are rigidly secured by dowelpins or bolts .2 F, is a sheet metal deck or wall located between, andbolted to, the side walls or runners of the respective sleds.

G, denotes a transverse shaft journaled in the frame and fitted at eachend with a spool G, to respectively receive the on d of a cable H,connected to each side of the forward sled. I, indicates a worm gear onthe shaft G, in mesh with a worm gear I, on the lower end of thesteering column P, which is in turn suitably journaled in the frame and'irovjhled with a steering wheel F, for manually rotating it.

Projecting rearwardly from the end of the vehicle is a pair of screwpropellers J, J, spaced apart and respectively secured to a pair ofshort shafts J, J, in turn connected by universal joints L, with thestub shafts M, journaled in a transverse member N, of the frame. Fittedto the end of the shafts M, M, is a sprocket gear 0, driven by asprocket chain P, from a gear P, P, actuated by intermeshing spur gearsP P, from the driving shaft P which is in turn actuated by a prime mover(not shown).

Bolted. to the frame at each side of the vehicle is an arc-shapedraclcbar Q, and extending transversely thereto is a shaft R,

journa-led in movable bearings R,through which the shafts J J, also passbut at right angles thereto.

K, K, are pinions mounted on the shaft B, respectively in mesh with therack bars Q. R is amovable bearing for the shafts J, J, adapted to slidealong the back of the rack bars. Mounted on the shaft R, is a sprocketwheel S, to receive the sprocket chain S-in turn guided by suitableidlers S The sprocket chain S, is actuated by a sprocket gear T, keyedto a short shaft T, journaled in brackets T bolted to the frame. U, is ashaft manually operated by means of a hand wheel U, on the lower endof-which is a gear U in mesh with a gear T carried by the shaft T. Uponmanually adjusting the shaft U, the sprocket gear T, will operate thesprocket chain which in turn will operate sprocket wheel S, and therebythe pinions K, K, on the shaft R, thus raising or lowering thepropellers J, J, quirements necessary "for different snow.

Instead of using a sprocket chain for raising and lowering thepropellers, a shaft 1), may be employed (see Fig. 10), fitted with apinion b, on one end of the shaft in mesh with the gear T and a gear 6at the opposite end of the shaft in mesh with a gear S on the shaft R;-earrying the pinions K, in mesh with the rack bars. By operating thehand wheel U, the propeller J, J, may be raised or lowered as required.

Between the prime mover (not shown) and the driving shaft P is asuitable clutch mechanism (not shown) to disconnect the propellingmechanism from the prime mover as in the case of anautomobile.

The respective parts having been indicated by reference letters, theconstruction and operation of the device will now be understood withoutfurther detailed explanation.

Having thus described my invention, what I claim is 1. In a motor drivensleigh, a chassis, a

depths of to meet the rebody supported by the chassis, a sled rigidlysecured to the rear end of the chassis, a sled pivoted to the forwardend of the chassis,

manually operated means for steering the r forward sled, apair of screwpropellers projecting from the end of a-pair of shafts journaled inmovable bearings at the rear of the chassis, a prime mover, a drivingshaft actuated by the prime mover, a driving connection between thedriving shaft and the shafts for supporting the screw propellerincluding a universal joint, whereby the screw propellers may be rotatedand also raised or lowered to adapt them to the depth of the snow overwhich the vehicle travels, and means for raising and lowering saidpropellers.

2. In a motor driven sleigh, a chassis, a sled rigidly secured to therear end of the chassis, a sled having a fifth wheel connection with theforward end of the chassis, manually operated means for steering saidlast named sled, a pair of screw propellers carried on the end of a pairof shafts journaled in movable bearings, a transverse shaft alsojournaled in said bearings fitted with pinio'ns adapted to transverse apair of rack bars, the rack bars, manually operated means for rotatingsaid transverse shaft, whereby it may raise and lower said movablebearings and the sh, f

ts journaled therein, a prime mower, a dr: ing shaft actuated by theprime mover, a. driving connection between the driv'ng shaft and theshafts of the screw propellers including a universal joint, whereby thescrew propellers ina be rotated and also raised or lowered to adapt themto the depth of snow over which the vehicle travels.

In testimony whereof I sign this specification in the presence of twowitnesses,

JOHN PASKO.
